Hey thanks, you beat me to it!!

I've encountered four very aggressive and frightening dalmatians, one aggressive golden retriever, and one aggressive greyhound (as well as a myriad of nasty "toy" sized dogs) in the last few years that I've been working around animals every day....but I've yet to encounter an aggressive pit bull. Maybe I just haven't come across enough yet? I don't know.
